MAYBE START THE TRAILER WITH YASEEN BEING DEFEATED AND ON THE GROUND. AND THEN SHOW A FAST REWIND BACK TO HOW HE GOT THERE (BASICALLY THE BUILD UP TO THAT SCENE) WHICH IS WHEN THE MUSIC WOULD START. FIRSTLY SOME NORMAL SCENES OF HIM AND SARA WITH THEIR INTRODUCTION SUCH AS "YASEEN (WEATHER BOY)" OR "YASEEN AS WEATHER BOY". SARA IS JUST SARA LOL. BUT NO ACTOR NAMES PLEASE. AND THEN A SCENE OF HIM GAINING HIS POWERS AFTER BEING STRUCK BY LIGHTNING (YOU DONT HAVE TO SHOW THAT PART BUT MAYBE JUST A SCENE TO SHOW HIM SUDDENLY HAVING SMALL POWERS AND EXPERIMENTING/BEING CONFUSED ABOUT IT). AND THEN HIM MEETNG THE OTHER CAST MEMBERS SO MAYBE HAVE THEIR INTRODUCTIONS QUICKLY AT THIS POINT AND THEN THE MAIN FIGHT SCENES WITH ALL OF THEM AGAINST THE SUPERVILLAIN. CAN BE ANY SUPERVILLAIN BUT MORE EMPHASIS SHOULD BE ON THE POWERS INSTEAD OF THE PEOPLE (SUCH AS LIGHTNING AND STORMS AND STUFF). SO WHILE THE FIGHT SCENE IS HAPPENING MAYBE HAVE THE TEXT IN BETWEEN AND THEN END IT WITH A RAIN SCENE BEFORE THE TITLE APPEARS IF THAT MAKES SENSE. FINALLY, THE CREDITS ETC

THIS IS JUST A SUGGESTION BUT HONESTLY ANYTHING IS FINE AS LONG AS THERE ARE SOME SUPERHERO FIGHT SCENES TO GIVE THE SUPERHERO THEME ESPECIALLY THINGS LIKE LIGHTNING OR HEAVY RAIN AS THE BOOK IS MOSTLY WEATHER POWER RELATED
